provide increased protection for the head but
not the chest or arms.

:
are deployed
R
on the impacted side of the vehicle
R
in instances with a high rate of lateral
vehicle deceleration or acceleration
R
regardless of whether the front passenger
seat is occupied
R
independently of the front air bags
The window curtain air bags are not deployed

Occupant Classification System
The Occupant Classification System (OCS)
activates or deactivates the front passenger
front air bag automatically. The respective
status is based on the classified occupant
weight category determined by weight sensor
readings from the front passenger seat.
The system does not deactivate
R
the front passenger side impact air bag
R
the window curtain air bag
R
the Emergency Tensioning Devices (ETDs)
To be classified correctly, the front passenger
must sit
R
with the seat belt properly fastened
R
in a position that is as upright as possible
with the back against the seat backrest
R
with the feet on the floor
If the occupant’s weight is transferred to
another object in the vehicle (e.g. by leaning
on armrests), the OCS may not be able to
properly approximate the occupant’s weight
category.
Furthermore, the occupant weight may
appear to increase or decrease due to the
following: objects hanging on the seat, lodged
underneath the seat, stuffed between the
seat and middle console or the seat and door,
other passengers pushing on the seat, or
objects applying pressure to the back of the
seat. Always make sure the seat has
clearance in all directions at all times.
If your seat, including the trim cover and
cushion, needs to be serviced in any way, take
the vehicle to an authorized F-CELL Service
Center.
Only seat accessories approved by
Mercedes-Benz may be used.
Both the driver and the front passenger
should always use the
